Answer:
360
Step-by-step explanation:
If we originally have 9 red cubes, 5 green cubes, and 11 blue cubes, if we add these, we have to:
9 + 5 + 11 = 25
This means that the probability of network cubes of 9/25, now without 1000 pulls, would be:
1000 * 9/25 = 360
That means that about 360 red cubes are expected, probably
Answer:
y = 0.5x +10
Step-by-step explanation:
If x represents the number of days since Rosie planted her tomato plant, then 0.5x is the number of centimeters it has grown. This growth is added to its initial height (10) to get the number of centimeters high the plant is after x days:
y = 0.5x +10
I think it’s the first one (the one you chose in the pics).
Distribute 6(x+4) = 8(x-2)
6x+24 = 8x-16 subtract by on both sides
-24. -24
6x = 8x-40 subtract by on both sides
-6x. -6x
2x = -40
divide both by 2 on each side
and X=20
Don't get confused with the second pair of brackets - you must apply the negative sign on the outside to all the signs on the inside, which now gives:
Now just take away the brackets and collect like terms to get:
